Cement flooring screed additive TamCem NanoSilica

for concrete

TamCem NanoSilica is a pozzolanic alternative to traditional cementitious replacements for durable concrete that provides sulphate resistance equivalent to typical microsilica (silica fume) at a much-reduced dose. TamCem NanoSilica is used in wet mix sprayed concrete processes for tunnelling and mining applications. The product is suited as an addition to concrete providing improved fresh state and hardened properties. Importantly, TamCem NanoSilica enhances durability of permanent sprayed concrete ground support. Such durability enhancement includes excellent resistance to underground structures exposed to high sulphate and chloride containing groundwater and ground types. Key Benefits A very active pozzolan that imparts excellent durability performance for concrete and sprayed concrete, such as sulphate and chloride resistance. Can be used with CEM I and CEM II cement types, providing enhanced durability coupled with greater early age strength performance. Improved final compressive strength and reduced permeability. Reduces bleeding and segregation of concrete mixes, improves cohesion and aids pumpability. Added at batching plant with standard admixture dosing equipment without the safety precautions and special dosing equipment associated with silica fume (microsilica) handling. Site logistics improved as lower dosage of product required. Stable dispersion that does not require agitation in order to retain its suspension. Used to produce high performance concrete.
